The pituitary tumor, as it grows, often starts to compress the visual nerves in your brain, with the result that people with acromegaly have either double vision or they are profoundly nearsighted.

What I am trying to do is I'm trying to bring those two views into one so that my images both speak to the viewer's heart but also to the viewer's brain.

By stimulating the good memories that will be stored in the amygdala, the emotional storage of the human brain.

Well, as Chris pointed out, I study the human brain, the functions and structure of the human brain.

Well, there are many ways of approaching the functions of the human brain.

One approach, the one we use mainly, is to look at patients with sustained damage to a small region of the brain, where there's been a genetic change in a small region of the brain.

What you get is a highly selective loss of one function, with other functions being preserved intact, and this gives you some confidence in asserting that that part of the brain is somehow involved in mediating that function.

And that's been called the face area in the brain, because when it's damaged, you can no longer recognize people's faces.

It's the only interpretation that makes sense to your damaged brain.

So, to explain this curious disorder, we look at the structure and functions of the normal visual pathways in the brain.

Normally, visual signals come in, into the eyeballs, go to the visual areas in the brain.

There are, in fact, 30 areas in the back of your brain concerned with just vision, and after processing all that, the message goes to a small structure called the fusiform gyrus, where you perceive faces.

You can call it the face area of the brain, right?

But from that area, the message cascades into a structure called the amygdala in the limbic system, the emotional core of the brain, and that structure, called the amygdala, gauges the emotional significance of what you're looking at.

But maybe, in this chap, that wire that goes from the amygdala to the limbic system, the emotional core of the brain, is cut by the accident.

It's a lovely example of the sort of thing we do: take a bizarre, seemingly incomprehensible, neural psychiatric syndrome and say that the standard Freudian view is wrong, that, in fact, you can come up with a precise explanation in terms of the known neural anatomy of the brain.

The reason is there's a separate pathway going from the hearing centers in the brain to the emotional centers, and that's not been cut by the accident.

OK, how is all this complex circuitry set up in the brain?

When the arm was intact, but paralyzed, the brain sends commands to the arm, the front of the brain, saying, "Move," but it's getting visual feedback saying, "No."

And this gets wired into the circuitry of the brain, and we call this learned paralysis, OK?

The brain learns, because of this Hebbian, associative link, that the mere command to move the arm creates a sensation of a paralyzed arm.

It's because the brain is faced with tremendous sensory conflict.

And your motor command saying there is an arm, and, because of this conflict, the brain says, to hell with it, there is no phantom, there is no arm, right?

So, we found that the color area and the number area are right next to each other in the brain, in the fusiform gyrus.

So we said, there's some accidental cross wiring between color and numbers in the brain.

So, every brain region is wired to every other region, and these are trimmed down to create the characteristic modular architecture of the adult brain.

So, if there's a gene causing this trimming and if that gene mutates, then you get deficient trimming between adjacent brain areas.

Now, what if this gene is expressed everywhere in the brain, so everything is cross-connected?

Now, if you assume that this greater cross wiring and concepts are also in different parts of the brain, then it's going to create a greater propensity towards metaphorical thinking and creativity in people with synesthesia.

It's a primitive form of abstraction, and we now know this happens in the fusiform gyrus of the brain, because when that's damaged, these people lose the ability to engage in Bouba Kiki, but they also lose the ability to engage in metaphor.
